The official charge sheets accuse the two Navy SEALs and two Marines of breaking into Melgar’s bedroom, physically restraining him with duct tape and placing him in a chokehold.

The charge sheets say the murder took place while the accused were “perpetrating a burglary.”

The four service members are also accused of lying to investigators.

One of the Navy SEALs was charged with performing a cricothyrotomy on Melgar’s body to cover up the injuries to his trachea. A cricothyrotomy is normally an emergency lifesaving medical procedure that involves making an incision in the trachea to establish an airway.

The Article 32 preliminary hearing for the four accused is currently scheduled for December 10.

“We honor the memory of Staff Sgt. Melgar, our thoughts remain with his family and teammates,” US Navy Capt. Jason Salata, a spokesman for US Special Operations Command, told CNN.

“If these allegations of misconduct are substantiated, they represent a violation of the trust and standards required of all service members. We trust our service members to safeguard our nation’s most sensitive interests and to do so with honor,” Salata added.

Earlier this month, the Naval Criminal Investigative Service sent its report on the investigation into Melgar’s death to Rear Adm. Charles Rock, the commander of Navy Region Mid-Atlantic, in order to “make determinations regarding administrative or disciplinary actions as appropriate.”

Secretary of the Navy Richard V. Spencer ordered Rock to oversee see disciplinary actions relating to Melgar’s death in late October.

Military officials told CNN last year that a military examiner had ruled Melgar’s death at a US government compound, near the American embassy in the capital of the West African nation, was a homicide.

The Navy took over the investigation from the Army in September 2017.

CNN previously reported that two members of SEAL Team Six were under investigation.

Melgar’s cause of death was asphyxiation, according to a defense official familiar with the findings of the medical examiner’s report.

Melgar, a native of Lubbock, Texas, enlisted in the US Army in 2012 and began Special Forces training in 2013, according to the US Army Special Command statement. He served two deployments to Afghanistan.
